3G usage woldwide ?

Hi,
I recently bought a T-Mobile MDA Vario III from T-Mobile Netherlands.
Visiting the US I discovered this phone does not support 3G in the US.
My US colleague liked the phone so much, and had a look at the AT&T Tilt. The big difference is ofcourse the missing frontcamera, but this one works in the US on 3G. Are there any AT&T Tilt users here that have tried that phone in Europe and/or Asia and got 3G or HSDPA there ?
I suspect there are different versions of this phone around with different frequency support. Or should I have bought a HTC version, are they possibly enabled to use 3G in both US, Europe and Asia ?
Any hints to enable 3G on my phone while visiting the US would be appreciated !
Regards,
Taco
Umm, unless the Vario III is crippled (in terms of frequencies supported), the Kaiser supports all currently 3G frequencies worldwide - 850, 1900, 2100MHz. I used my TyTN II in Korea (2100) and obviously in the US (850/1900)...According to gsm.org, Netherlands TMo uses 2100 also.

T-Mobile USA does not yet have 3G. They'll be on the the new bands someday (and your Kaiser doesn't support those bands). Most likely you'd find yourself on the T-Mobile network with GSM-only.
If you want 3G in the US, you'll probably need to purchase a prepaid card from AT&T...
I can swith to the AT&T network with no problem, still only Edge....
What I am suspecting is that 3G is on different frequencies/bands in the US, and the european models don't support them ....
Question still remains: has a AT&T Tilt user been to Europe or Asia and saw that 3G worked there ? My colleague wants to buy one ...
Thanks !

The Tilt defintiely works in Asia and Europe. And I'm fairly certain that the Vario III will work on 3G in the US as well.

This is conjecture on my part, but I'll bet that T-Mobile Europe and AT&T do not have a 3G roaming agreement in place in the US...

Can I take advantage of 3G connection in Europe with AT&T USA branded Kaiser?

Hi All,
I currently live in the USA and I have a AT&T branded Kaiser and a Hyperdragon III BlackStone ROM on T-Mobile USA network.
I know that the phone does not actually support T-Mobile's USA 3G network but could anyone tell me if I can take advantage of the European 3G networks with this phone? I'll be travelling in the UK and Spain and would really like to use it as amodem for my laptop when there is no wifi around.
Any info would be appreciated
anyone know?

[Q] Will HTC HD7 (T-Mobile) work in India for 3G?

Hello All,
I have brought an unlocked HTC HD7 (T-Mobile) from USA and according to the specs given at HTC US site, It says that it supports UMTS 2100 and AWS 1700/2100 band for 3G.
Can anyone confirm on having used HTC HD7 (T-Mobile) in India on Tata DoCoMo or BSNL network for 3G?
Thanks
Shaju
well, i already bought mine from us and i use it in Saudi Arabia with no problems at all with 3g, just to be sure contact your telecom company and ask them if it is supported or not.
regards
Theoretically, yes, it should work.
I'll be giving it a shot on Vodafone (in Mumbai) once they launch their 3G service, shortly, but if anyone else has confirmation, that'd be great to know.
Hello saud_19, what is 3g band used by your service provider? Is it UMTS 2100 or AWS 1700/2100?
Thanks,
Shaju
well Shaju, unfortunately i am not sure but i think it is 2100.
: )

Most likely you wont get much out of your HD7 cellphone in india..
you will be combarded with spam because thats where all the marketing place is ring ring and they spam you with advertice. Infact indian doesnt have the best coverage at all... its a poor country to beging with.
Its best you buy a phone that works in your town and that make sure it has coverage all over with your local provider.

First of all lemme tell you all, that HD7 works great in India, got hold of one in Nov last year and have been using it with impressive results.
There are some issues with the marketplace, but a workaround is available.
Secondly about India being poor, I guess this is not the forum to take offense, to what clearly is OFFENSIVE.
3g services are lagging, as its still in a nascent stage. I'm getting between decent to good speeds on Airtel 3g in Delhi
Cheers

Dumb-ass ignoramus comments.
A TMOUS HD7 will get 3G on 2100 band.
Great, this means I won't regret my impulse buy of a TMOUS HD7 last week.
It works too where I live, we a UMTS 2100 network. But speed sucks!! think it does not support hsdpa speeds on UMTS 2100 networks cuz mine cant get pass 35KB/s download speed

[Q] O2 HD7 on Wind Mobile (AWS)

I have an unlocked 02 HD7 which I brought with me before emigrating from the UK.
I am currently using it on Rogers, however I am thinking of upping sticks and moving to windmobile which is AWS. I know that the HD7 was sold be TMO US so it is AWS compatible but was this a different hardware to the O2 version or is there a way to get it to work on AWS (radio rom flash etc.)
Thanks
Tim
Shameless bump, anyone know the answer. Or alternatively know if you can use a Euro HD7 on TMo US?
Tim
From what i know about O2 is that they don't use the same frequencies as such changing the radio version won't do any good as the physical antenna design wont work with the AWS frequencies. your best bet would be to sell the HD7 and buy a new one a Tmo version. I bought mine about a week ago for $425CAD in Toronto and am now using it on Wind.
They're different hardware. The Bell HD7 doesn't work on WIND for the same reason.
Thanks for you help, hoped it wasn't the answer but guess I will sell up and move on.

Unlocked HD7 Question

Just picked up an HD7 for real cheap wanted to play around with it however I have ATT I got the phone unlocked and receiving data but I am only at edge speeds any way to get the 3g to work thanks in advance!
It sounds to me like the unlocked phone you got was a T-Mobile model. T-Mobile and AT&T use different frequencies for 3G so it simply isn't possible to use a phone from one on the other and still get 3G service. Yeah, it works both ways, you can't get 3G on an unlocked iPhone with T-Mobile, for example.
Depends on the phone. Unlocked Vibrant works on ATT 3g
Sent from my GT-I9000 using XDA Premium App
If your phone was from TMo-US, you'll only get EDGE, as Tmo uses 900/2100. ATT uses 850/1900. You need a Telstra/Bell unlocked HD7.
Look at your "About" screen. T9295 is what you should see. T9292 is TMo-US.
Hi all,
I also got T9295 from AT&T,
I'm in France but I can't run 3G, only edge.
Any Idea?
Is it a Hardware limitation or just software?
thanks in advance for your help.

it's a hardware limitation, no way on earth you can run 3G on your AT&T HD7S, unless if you have an operator that uses the same frequencies as ATT
Thanks for your fas reply.
much appreciated!!
I'm in germany but I can't run 3G, only edge.

Yeah, but the ATT HD7S has some HW limitations, and it only support 1900MHz
